The root note is the note after which the chord is named. It is indicated by a square placed around the note on the fretboard diagram.
The root note of an F major chord is an F note. In the F major bar chord shape at the end of the previous lesson this root note is on the first fret of the 6th string. Because the root note is on the 6th string this bar chord shape is called a root 6 chord. This bar chord shape will always have its root note on the 6th string. e.g.:
If this bar chord shape was played at the 12th fret it would be an E major chord. After the 12th fret the names of the notes (and chords) will start repeating. If this bar chord shape was played at he 15th fret it would be a G major chord.
Play the following root 6 bar chord progression using an open chord shape for the E major chord and root 6 bar chord shapes for the G major, A major and C major chords.
When changing between chord shapes, release the pressure of your left hand but do not let your left hand fingers lose contact with the strings. This will make the chord changes easier because your fingers are still in the correct shape and all you have to do is glide them along the strings to the next chord position. These root 6 bar chord shapes are sometimes called E formation because they are based upon an open E chord.
The following two chord progressions use only root 6 bar chords. The D chord is played with the first finger barring the 10th fret. The B flat (Bb) chord is played with the first finger barring the 6th fret.
